Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of plate strip finishing, and particularly relates to a high-speed trimming line scrap edge vacuum suction and treatment system. BACKGROUND

[0002] At present, in the thin strip trimming production line, the scrap edge of the strip cut by the disc shear is generally cut off by the scrap cutter, or the scrap edge is directly wound by the edge winding machine. The speed of the unit directly wound by the scrap cutter and the edge winding machine is usually not too high, and the speed of the unit is usually below 800 m / min.

[0003] In the production process of some thin strip high-speed trimming line, the scrap edge treatment process technology of the scrap cutter and the edge winding machine directly wound cannot process the scrap edge of the high-speed cutting of the unit, and cannot meet the needs of the high-speed production of the thin strip. For example, in the production process of pot material aluminum, the thickness of the aluminum material is usually not more than 0.27 mm, and the thinnest aluminum material thickness can even reach 0.1 mm, and the aluminum coil diameter is large (the maximum coil diameter reaches 2800 mm), and the factory requires high output (such as a domestic aluminum factory requires the annual output of pot aluminum coil to be 120 kt / y), and the unit speed is required to be high (the highest unit speed reaches 1500 mm / min) to meet the market needs. The running speed of the scrap cutter itself cannot keep up with the high speed of the unit, and there is a problem of synchronization between the scrap cutter and the disc shear. If the running speed of the scrap cutter is higher than that of the disc shear, the scrap edge is easy to break, and if the running speed of the scrap cutter is lower than that of the disc shear, the scrap edge is easy to accumulate in front of the scrap cutter, which will cause production accidents. The production mode of directly winding the scrap edge by the edge winding machine also cannot meet the requirements of high-speed operation of the unit. When the unit runs at high speed, the high-speed running scrap edge will move irregularly and randomly when meeting air resistance, and will accumulate at the outlet of the disc shear, causing production accidents. If the edge winding machine pulls the scrap edge winding, there is also a problem of speed synchronization. If the speed of the edge winding machine pulling the scrap edge is too fast, the scrap edge is easy to break, and if the speed of the edge winding machine pulling the scrap edge is too slow, the scrap edge is easy to accumulate at the disc shear, which also causes production accidents.

[0004] Moreover, the process scheme of directly processing the scrap edge by the scrap cutter and the edge winding machine will generate a large amount of dust, seriously affecting the production working environment of the workers, causing dust pollution, and directly threatening the occupational health of the workers.

[0005] In the production process of very thin tinplate, there are also similar problems.

[0006] Therefore, a new scrap edge treatment scheme for high-speed trimming line is needed to meet the needs of high-speed operation of the unit. SUMMARY

[0007] In order to overcome the above-mentioned defects of the prior art, the purpose of the present application is to provide a high-speed trimming line scrap edge vacuum suction and processing system for processing the scrap edge problem of a high-speed trimming unit, meeting the requirements of high-speed operation of the unit, solving the environmental pollution problem generated in the production process, purifying the working environment, and solving the speed synchronization problem between the unit equipment, thereby eliminating the production accidents caused by scrap edge belt breakage or accumulation blockage.

[0039] The technical solutions of the application will be further described in combination with the drawings and specific embodiments.

[0040] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the high-speed trimming line scrap edge vacuum suction and processing system provided by the embodiment of the application is composed of a blowing device 1, a main pipeline 2, a support 3, a scrap edge interface device 4, a branch pipeline 5, a scrap edge clamping device 6, a crimping machine 7, a crimping machine closed chamber 8 and a dust removal device 9.

[0041] As shown in Figure 1 , the fan 1.3 of the blowing device 1 sends high-speed airflow into the main pipeline 2, and the high-speed airflow enters the branch pipeline 5 through the second electric butterfly valve a and the second pressure sensor P on the main pipeline; a bypass pipeline is further arranged on the main pipeline 2, and the first electric butterfly valve a is installed on the bypass pipeline to adjust the size and pressure of the high-speed airflow on the main pipeline; the main pipeline 2 and the branch pipeline 5 are connected through a hose, and the high-speed airflow forms a vacuum at the end of the branch pipeline 5 to suck the scrap edge after being cut by the disc shear and the dust generated by the cutting into the branch pipeline 5; the scrap edge enters the scrap edge clamping device 6 through the branch pipeline 5, the scrap edge clamping device 6 clamps and sends the scrap edge into the crimping machine 7, the crimping machine 7 winds and takes up the scrap edge, and the dust enters the crimping machine closed chamber 8 through the branch pipeline 5; the dust removal device 9 sucks away the dust in the crimping machine closed chamber 8, collects the dust and discharges the dust into a dust collecting box.

[0042] As shown in Figure 1 and Figure 4As shown, the air supply device 1 mainly consists of a ventilation fan 1.1, a silencer 1.2, a fan 1.3, a fan room 1.4, a first electric butterfly valve a, a first pressure sensor P, etc. The fan 1.3 is installed in the fan room 1.4, and the ventilation fan 1.1 and the silencer 1.2 are installed on the roof of the fan room 1.4. A bypass pipe is arranged on the outlet main pipe 2 of the fan 1.3, and the bypass pipe is provided with the first electric butterfly valve a and the silencer 1.2. The ventilation fan 1.1 is used to discharge the heat generated during the operation of the fan 1.3. The first pressure sensor P is used to detect the pressure of the high-speed airflow in the pipeline. The first electric butterfly valve a is used to adjust the high-speed airflow and the pressure in the pipeline. The silencer 1.2 is used to eliminate or reduce the noise generated by the high-speed airflow at the outlet of each pipe.

[0043] As shown in Figure 1 and Figure 3 , the main pipe 2 is connected to the outlet of the fan 1.3. The main pipe 2 is provided with a second electric butterfly valve a and a second pressure sensor P. The pipe 2.1 is a flexible pipe connected to the waste edge interface device 4.

[0044] As shown in Figure 2 , the bracket 3 is used to support the main pipe 2 and the branch pipe 5.

[0045] As shown in Figure 5 , Figure 6 and Figure 7As shown, the waste edge interface device 4 is composed of a third electric butterfly valve a, a pipeline 4.1, a cross ball cage joint 4.2, a movable seat 4.3, a fixed base 4.4, a linear guide rail 4.5, an encoder 4.6, a ball screw 4.7, a gas cylinder 4.8, a motor 4.9 and an extension pipe 4.10. The third electric butterfly valve a is installed on the pipeline 4.1 for adjusting the pressure and flow of high-speed airflow in each branch pipeline. The cross ball cage joint 4.2 is installed on the pipeline 4.1. The extension pipe 4.10 is installed in the pipeline 4.1. The pipeline 4.1 is installed on the movable seat 4.3. The movable seat 4.3 is installed on the fixed base 4.4 through the linear guide rail 4.5. The ball screw 4.7 is installed on the fixed base 4.4 and drives the movable seat 4.3 to move. The encoder 4.6 and the motor 4.9 are installed at both ends of the ball screw 4.7. The gas cylinder 4.8 is installed on the pipeline 4.1 and drives the extension pipe 4.10 to move. When the disc shear shears the strip width changes, the motor 4.9 drives the ball screw 4.7 to rotate, thereby driving the movable seat 4.3 to move horizontally. At the same time, the encoder 4.6 at the end of the ball screw 4.7 starts counting to ensure that the width of the two pipelines 4.1 meets the requirements of the strip shearing width. At the same time, the gas cylinder 4.8 drives the extension pipe 4.10 to move forward, so that the extension pipe 4.10 reaches the disc shear shearing area. The high-speed airflow forms a vacuum area in the extension pipe 4.10, which sucks in the waste edge and dust generated by the disc shear shearing. When the disc shear changes blades or is maintained, the extension pipe 4.10 is retracted to provide more operation space for the disc shear maintenance.

[0046] As shown in Figure 2 and Figure 3 , one end of the branch pipeline 5 is connected to the cross ball cage joint 4.2, and the other end is connected to the waste edge clamping device 6.

[0047] As shown in Figure 8 , Figure 9 and Figure 10As shown, the scrap edge clamping device 6 includes a servo motor 6.1, a scrap edge clamping frame 6.2, a pneumatic cylinder 6.3, a fixed roller 6.4, and a swing roller 6.5. The servo motor 6.1, the pneumatic cylinder 6.3, the fixed roller 6.4, and the swing roller 6.5 are all mounted on the scrap edge clamping frame 6.2. The servo motor 6.1 is connected to the shaft end of the fixed roller 6.4 and drives the fixed roller 6.4 to rotate. The pneumatic cylinder 6.3 drives the swing roller 6.5 to swing. When the scrap strip head is introduced, the pneumatic cylinder 6.3 drives the swing roller 6.5 to open, the scrap strip head enters between the fixed roller 6.4 and the swing roller 6.5, the pneumatic cylinder 6.3 drives the swing roller 6.5 to swing, the fixed roller 6.4 and the swing roller 6.5 jointly clamp the scrap strip head, and the servo motor 6.1 drives the fixed roller 6.4 to rotate to pull the scrap strip head into the edge curling machine 7. The linear speed of the servo motor 6.1 driving the fixed roller 6.4 to rotate is slightly higher than the speed of the unit, so that the scrap edge is in a small tension state, and the scrap edge will not accumulate in the pipe under the double action of high-speed airflow and pinch rollers (formed by the fixed roller 6.4 and the swing roller 6.5); when the scrap edge is accidentally pulled off, the scrap edge enters the pinch rollers (formed by the fixed roller 6.4 and the swing roller 6.5) under the blowing of high-speed airflow, and then enters the edge curling machine, so that the scrap edge will not accumulate in the pipe. Therefore, the combined action of high-speed airflow and pinch rollers (formed by the fixed roller 6.4 and the swing roller 6.5) solves the problem of scrap edge processing of the thin strip high-speed slitting unit, so that the unit can produce at high speed; at the same time, it solves the problems of speed synchronization such as scrap strip breakage and scrap strip accumulation; at the same time, the high-speed airflow brings the dust generated by the disc shear into the closed chamber 8 through the pipe, and finally discharges the dust through the dust removal equipment 9.

[0048] As shown in Figure 2 , Figure 3 and Figure 4 , the scrap edge clamping device 6 is mounted on the edge curling machine fixed frame 7.4.

[0049] As shown in Figure 11 , Figure 12 and Figure 13As shown, the edge curling machine 7 includes a transmission reel 7.1, a transmission base 7.2, a hydraulic cylinder 7.3, an edge curling machine fixed frame 7.4, a hydraulic cylinder 7.5, a hydraulic cylinder 7.6, a baffle 7.7, and a pressure roller 7.8. The transmission reel 7.1 is installed on the transmission base 7.2 and is driven to rotate by a motor; the hydraulic cylinder 7.3 is installed on the transmission base 7.2 and drives the transmission reel 7.1 to move horizontally; the hydraulic cylinder 7.5, the hydraulic cylinder 7.6, the baffle 7.7, and the pressure roller 7.8 are all installed on the edge curling machine fixed frame 7.4; the hydraulic cylinder 7.5 drives the pressure roller 7.8 to move; and the hydraulic cylinder 7.6 drives the baffle 7.7 to move. When the waste strip is threaded and led, the hydraulic cylinder 7.3 drives the transmission reel 7.1 to enter the edge curling machine fixed frame 7.4, the hydraulic cylinder 7.6 drives the baffle 7.7 to close, the hydraulic cylinder 7.5 drives the pressure roller 7.8 to move and open, the motor drives the transmission reel 7.1 to rotate, and the head of the waste strip starts to wind on the transmission reel 7.1. At this time, the hydraulic cylinder 7.5 drives the pressure roller 7.8 to move and press the waste strip, so that the waste strip is wound more densely. When the detection instrument detects that the waste edge is wound to a certain extent, at this time the hydraulic cylinder 7.5 drives the pressure roller 7.8 to open, the hydraulic cylinder 7.6 drives the baffle 7.7 to open, and the hydraulic cylinder 7.3 drives the transmission reel 7.1 to exit the working position, and the waste roll will roll off to the designated collection position.

[0050] The edge curling machine fixed frame 7.4 is installed in the edge curling machine closed chamber 8.

[0051] As shown in Figure 1 and Figure 2 As shown, the dust removal equipment 9 includes a silencer 9.1, a fan 9.2, a dust collector 9.3, and a valve 9.4. The dust removal equipment 9 sucks away the dust generated by shearing and the dust generated by waste edge winding in the closed chamber 8 through a pipeline.

[0052] When the thickness of the produced strip changes, the opening degree of the butterfly valve a on the bypass pipeline of the main pipeline can be adjusted, so as to control the pressure and flow of the high-speed airflow on the main pipeline to meet the production needs of different thicknesses.

[0053] When the disc shear shears the two waste edges with different widths, the opening degrees of the butterfly valves a on the two branch pipelines can be adjusted respectively, so that the opening degree of the butterfly valve on the branch pipeline on the wide waste edge side is greater than that on the branch pipeline on the narrow waste edge side, and the flow of the high-speed airflow on the branch pipeline on the wide waste edge side is greater than that on the branch pipeline on the narrow waste edge side, so as to adjust the suction of the two branch pipelines to meet the production needs.

[0054] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
